Memory Game Waves definitionsOnline version match the term to the definition by Dilini Wijayasinghe The time taken by a source to produce one wave An imaginary line drown through the crest of a wave perpendicular to the energy flow The length between two similar points in two consecutive waves The distance moved by the particle in a particular direction from the equilibrium point Angle subtended at the centre of a circle when the path of an oscillating particle of a wave is represented by the circumference of the circle. 1 wave produced by the source per second Wave, of which the particles oscillate parallel to the energy Maximum displacement of a particle from the equilibrium point The number of waves produced per unit time by a source Waves which transfer energy Waves, of which the particles oscillate perpendicular to the energy Distance moved my energy of the wave in a unit time
